Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to an automatic feeding device for machining. Background Technology

[0002] Machining refers to the process of altering the shape, size, or properties of a workpiece using mechanical equipment. In machining, any process that changes the shape, size, position, and properties of a production object to make it a finished or semi-finished product is called a technological process. It is a major part of the production process. Technological processes can be further divided into casting, forging, stamping, welding, machining, assembly, and other technological processes.

[0003] In the stamping process, in order to improve work efficiency, automatic feeding devices are currently used to transport metal sheet raw materials to operators. However, existing feeding devices transport metal sheet raw materials through conveyor belts. When feeding automatically via conveyor belts, metal sheet raw materials often pile up because operators cannot pick them up in time. In severe cases, this can cause the conveyor belt to jam, which seriously affects production efficiency.

[0004] In view of this, the present invention proposes an automatic feeding device for machining to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic feeding device for machining.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic feeding device for machining includes a feeding platform with an installation cavity inside. A through groove is provided on one side of the top of the feeding platform, communicating with the installation cavity. A connecting cavity is provided at the connection point between the through groove and the installation cavity. A push plate is slidably connected to the top of the through groove, and a push head is fixedly connected to one side of the push plate. Electric push rods are respectively provided at both ends of the push plate, and a connecting plate is provided between the electric push rods and the push plate. Four mounting frames are fixedly connected to one side of the top of the feeding platform, and each mounting frame is rotatably connected to a bidirectional threaded rod. The bottom end of each bidirectional threaded rod extends into the installation cavity, and threaded sliders are threadedly slidably connected above and below each bidirectional threaded rod. A connecting rod is hinged to one side of each of the two threaded sliders, and a clamping post is hinged to one end of each of the two connecting rods. Multiple metal discs are placed on the feeding platform, and the multiple metal discs are located between the four clamping posts. Multiple gear teeth are fixedly connected to the bottom outer wall of the push plate, and a transmission mechanism is provided between the gear teeth and the bidirectional threaded rods.

[0008] Furthermore, each of the clamping columns is fixedly connected to a mounting plate on one side of its bottom, and each mounting plate is equipped with a caster wheel at its bottom, the caster wheel being in contact with the surface of the loading platform.

[0009] Furthermore, the transmission mechanism includes a fourth gear, which is disposed inside the connecting cavity and meshes with gear teeth. Two slide rails are disposed below the fourth gear, and a rack is slidably connected between the two slide rails, which meshes with the fourth gear.

[0010] Furthermore, a rotating shaft is provided on one side of the rack two, and the rotating shaft is located at the center of the four bidirectional threaded rods. A gear three is fixedly connected to the outer wall above the rotating shaft, and a rack one is meshed on one side of the gear three. One end of the rack one is fixedly connected to the rack two.

[0011] Furthermore, a second gear is fixedly connected to the outer wall below the rotating shaft, and four first gears mesh with the outer wall of the second gear. The four first gears are respectively fixedly connected to the bottom outer wall of the bidirectional threaded rod.

[0012] Furthermore, a feeding trough is provided on one side of the top of the feeding platform, and conveying rollers are rotatably connected to the inner wall of the feeding trough. One of the conveying rollers has an opening directly below one end, and a pulley is fixedly connected to one end of the conveying roller. A rotary motor is provided on the inner wall of the bottom of the mounting cavity, and a pulley is fixedly connected to the output shaft end of the rotary motor. A belt is sleeved on the outer wall of the pulley, and the other end of the belt passes through the opening and is sleeved on the outer wall of the pulley.

[0013] Furthermore, each of the two adjacent conveyor rollers has a pulley three fixedly connected to one side of its outer wall, and the outer walls of the two pulley three located on the same vertical plane are fitted with the same belt two.

[0014] Furthermore, two rotating rollers are arranged directly above the feeding trough, and a conveyor belt is fitted on the outer wall of the two rotating rollers. A rotating motor is provided on one side of one of the rotating rollers.

[0015] Furthermore, multiple fixed posts are fixedly connected at equal intervals on the surface of the conveyor belt, and a connecting spring is fixedly connected to the top outer wall of each fixed post, and a pressing head is fixedly connected to the top of each connecting spring.

[0016] The beneficial effects of this invention are as follows:

[0017] By setting up a push plate, the push plate moves forward under the action of an electric push rod. During this movement, the transmission mechanism below the push plate enables multiple bidirectional threaded rods on the loading plate to rotate. Through the threaded slider and connecting rod, multiple clamping columns move towards the stacked metal discs. Thus, the four clamping columns can clamp and fix multiple metal discs (excluding the bottom one) from all directions, lifting them up. This allows the push head on the push plate to easily push out the bottom one, completing the feeding operation. When the push plate returns to its original position, the four clamping columns release the clamped metal discs, allowing the bottom one to be placed on the loading table surface. This cycle repeats, automatically completing the feeding of metal discs. This avoids the stacking and jamming issues that occur with traditional conveyor belt feeding methods, greatly improving feeding efficiency and increasing the speed of subsequent processing.

[0018] After the metal disc is fed out, its bottom outer wall will contact the conveying rollers in the feeding trough. The multiple conveying rollers in the feeding trough rotate under the drive of the rotary motor, which can automatically transport the metal disc above the feeding trough to the operator's material placement area, making it convenient for the staff to pick up and improving their processing efficiency.

[0019] By setting up a rotating roller, a second rotating motor, a conveyor belt, a fixed column, a connecting spring, and a pressing head, when the metal disc moves above the feeding trough, the second rotating motor moves the conveyor belt through the rotating roller, so that the pressing head can contact the surface of the metal plate. Through the elastic force of the connecting spring, the pressing head presses the metal plate, thereby preventing it from deviating during the conveying process. Attached Figure Description

Implementation

[0028] The technical solution of this patent will be further described in detail below with reference to specific embodiments. Example

[0029] Reference Figures 1-4 An automatic feeding device for machining includes a feeding platform 1, an installation cavity 15 inside the feeding platform 1, and a through groove 21 on one side of the top of the feeding platform 1, which communicates with the installation cavity 15. A connecting cavity 24 is provided at the connection between the through groove 21 and the installation cavity 15. A push plate 6 is slidably connected to the top of the through groove 21, and a push head 12 is fixedly connected to one side of the push plate 6. Electric push rods 14 are respectively provided at both ends of the push plate 6, and a connecting plate 13 is provided between the electric push rods 14 and the push plate 6. Four mounting frames 5 are fixedly connected to one side of the top of the feeding platform 1, and each mounting frame 5 is rotatably connected to a bidirectional threaded rod 8. The bottom end of the rod 8 extends into the mounting cavity 15, and each bidirectional threaded rod 8 is threadedly slidably connected to a threaded slider 10 above and below. Each of the two threaded sliders 10 is hinged to a connecting rod 9 on one side, and each of the two connecting rods 9 is hinged to a clamping column 4 at one end. The loading platform 1 holds multiple metal discs 3, which are located between the four clamping columns 4. Multiple gear teeth 23 are fixedly connected to the bottom outer wall of the push plate 6, and a transmission mechanism is provided between the gear teeth 23 and the bidirectional threaded rod 8. This mechanism can automatically complete the feeding of the metal discs 3, avoiding the stacking and jamming caused by the previous conveyor belt feeding method, greatly improving the feeding efficiency and increasing the speed of subsequent processing.

[0030] As a further embodiment of the present invention, each of the clamping columns 4 is fixedly connected to one side of the bottom of the mounting plate 7, and each mounting plate 7 is provided with a caster wheel 11 at the bottom. The caster wheel 11 contacts the surface of the loading platform 1 and can support the clamping column 11, so that the distance between the bottom of the clamping column 11 and the top outer wall of the loading platform 1 is slightly greater than the thickness of the metal plate 3, thereby making it easier for the clamping column 11 to stably clamp and fix the raw material located on the bottom metal plate 3, and avoid clamping the bottom metal plate 3.

[0031] As a further embodiment of the present invention, the transmission mechanism includes a gear 22, which is disposed inside the connecting cavity 24 and meshes with gear teeth 23. Two slide rails 25 are disposed below the gear 22, and a rack 26 is slidably connected between the two slide rails 25. The rack 26 meshes with the gear 22. When the push plate 6 moves, the gear 22 rotates through the meshing of multiple gear teeth 23 below the push plate 6 with the gear 22. The gear 22 then meshes with the rack 26, thereby enabling the rack 26 to move in the opposite direction to the push plate 6.

[0032] As a further embodiment of the present invention, a rotating shaft 20 is provided on one side of rack 26, and the rotating shaft 20 is located at the center of four bidirectional threaded rods 8. A gear 3 19 is fixedly connected to the outer wall above the rotating shaft 20, and a rack 17 is meshed on one side of the gear 3 19. One end of the rack 17 is fixedly connected to rack 26. When rack 26 moves, it will drive rack 17 to move synchronously. By meshing with gear 3 19 above the rotating shaft 20, rack 17 causes the rotating shaft 20 to rotate.

[0033] As a further embodiment of the present invention, a gear 218 is fixedly connected to the lower outer wall of the rotating shaft 20, and four gears 16 mesh with the outer wall of the gear 218. The four gears 16 are respectively fixedly connected to the bottom outer wall of the bidirectional threaded rod 8, so that the rotating shaft 20 will drive the gears 16 at the bottom of the four bidirectional threaded rods 8 to rotate through the gear 218 below, thereby causing the four bidirectional threaded rods 8 to rotate.

[0034] Working principle: Push plate 6 is moved forward by electric push rod 14. As push plate 6 moves, multiple gear teeth 23 below it mesh with gear 4 22, causing gear 4 22 to rotate. Gear 4 22 meshes with rack 2 26, thus pushing rack 2 26 in the opposite direction to push plate 6. The movement of rack 26 synchronously drives rack 1 17 to move. Rack 1 17 meshes with gear 3 19 above rotating shaft 20, causing rotating shaft 20 to rotate. Rotating shaft 20 then drives gear 1 16 at the bottom of four bidirectional threaded rods 8 via gear 2 18 below, causing the four bidirectional threaded rods 8 to rotate. This rotation is achieved through threaded slider 10 and connecting rods. 9. The multiple clamping columns 4 move toward the stacked multiple metal discs 3, so that the four clamping columns 4 can clamp and fix the multiple metal discs 3 (excluding the bottom metal disc 3) from all directions, lift them up, so that the push head 12 on the push plate 6 can easily push out the bottom metal disc 3, completing the feeding work. When the push plate 6 resets, the four clamping columns 4 release the clamped multiple metal discs 3, so that the bottom metal disc 3 is placed on the surface of the loading table 1. This cycle is repeated, so that the feeding work of the metal discs 3 can be completed automatically, avoiding the stacking and jamming situation that occurs when using the conveyor belt feeding method in the past, greatly improving the feeding efficiency and increasing the speed of subsequent processing. Example

[0035] Reference Figures 1-6 An automatic feeding device for machining, compared with embodiment 1, is provided with a feeding trough 2 on one side of the top of the feeding platform 1, and conveying rollers 28 are rotatably connected to the inner wall of the feeding trough 2. One end of the conveying roller 28 is provided with an opening 27 directly below it, and a pulley 32 is fixedly connected to one end of the conveying roller 28. A rotary motor 29 is provided on the bottom inner wall of the mounting cavity 15, and a pulley 30 is fixedly connected to the output shaft end of the rotary motor 29. A belt 31 is sleeved on the outer wall of the pulley 30, and the other end of the belt 31 passes through the opening 27 and is sleeved on the outer wall of the pulley 32. The rotary motor 29 can rotate the outermost conveying roller 28 by means of the pulley 30, the belt 31 and the pulley 32.

[0036] As a further embodiment of the present invention, pulleys 34 are fixedly connected to the outer wall of one side of two adjacent conveying rollers 28, and the outer walls of the two pulleys 34 located on the same vertical plane are fitted with the same belt 33. Through the transmission cooperation of multiple pulleys 34 and belt 33, multiple conveying rollers 28 in the feeding trough 2 can be rotated, thereby automatically conveying the metal plate 3 above the feeding trough 2 to the material placement area of ​​the operator, making it convenient for the staff to pick up and improving their processing efficiency.

[0037] Working principle: When the metal disc 3 is sent out, its bottom outer wall will contact the conveying roller 28 in the feeding trough 2. The multiple conveying rollers 28 in the feeding trough 2 rotate under the drive of the rotary motor 29, thereby automatically conveying the metal disc 3 above the feeding trough 2 to the material placement area of ​​the operator, making it convenient for the staff to pick up and improving their processing efficiency. Example

[0038] Reference Figures 1-7 An automatic feeding device for machining, compared with embodiment 2, has two rotating rollers 35 arranged directly above the feeding trough 2, and a conveyor belt 36 is sleeved on the outer wall of the two rotating rollers 35. A rotary motor 40 is provided on one side of one of the rotating rollers 35. When the metal disc 3 is conveyed and moved above the feeding trough 2 by multiple conveying rollers 28, the rotary motor 40 moves the conveyor belt 36 through the rotating roller 35.

[0039] As a further embodiment of the present invention, a plurality of fixed posts 37 are fixedly connected at equal intervals on the surface of the conveyor belt 36, and a connecting spring 39 is fixedly connected to the top outer wall of each fixed post 37. A pressing head 38 is fixedly connected to the top of each connecting spring 39. When the conveyor belt 36 rotates, it will drive the plurality of fixed posts 37 on its surface to move. During this process, the pressing head 38 at the top of the fixed post 37 will come into contact with the conveyed metal plate 3, thereby pressing the metal plate 3 under the elastic force of the connecting spring 39, preventing it from deviating during the conveying process.

[0040] Working principle: When the metal disc 3 is conveyed and moved above the feeding trough 2 by multiple conveying rollers 28, the rotary motor 40 moves the conveyor belt 36 through the rotating roller 35. When the conveyor belt 36 rotates, it will drive multiple fixed posts 37 on its surface to move. During this process, the pressing head 38 at the top of the fixed post 37 will contact the conveyed metal plate 3. Under the elastic force of the connecting spring 39, the pressing head 38 presses the metal plate 3, preventing it from deviating during the conveying process.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
